I am having some problems with running out of channels. I am on a windows 2000 server running MQ 5.3 CSD11. I believe that i have an application that is not terminating the connection properly. I have many connections in my netstat that say there are in a TIME_WAIT status connecting to my queue manager via a server conn connection. It seems as the application has terminated and i am just waiting for them to come back. i see this a usefulness because it will take less resources to re-establish this connection than creating a new one. Is this TIME_WAIT parm configurable? I have read some stuff about the Keep Alive interval but am not sure if this is what i need. i see keep alive more suitable for sdr/recv pairs not svrconn connections, am i mistaken?
Any input is welcome. |

What you're describing is a connection pool, such as is offered by WAS. However, if the application is not disconnecting properly I doubt if any mechanism will recognise the connection as available for re-use as it's still "in use" by the application.

If you have an app not closing the channels / connection you are in trouble... Get the connecting app fixed first.

Base MQ doesn't support connection pooling in the way you describe in your initial post.
You're better off tracing the application. All MQ can tell you is that the application isn't disconnecting, and you sort of know that......
